To quote in part:
"If the Mars Pathfinder had set down on the Red Planet billions
of years ago, it may have landed on a vastly different landscape,
one that could have been able to support life, space scientists
said on Thursday, March 4, 1999.
"Data collected from the 1997 Pathfinder mission, as well as the
Mars Global Surveyor project and the Viking missions of the 1970s, point to
a Martian climate that was wetter and warmer in its past, scientists said."
